Fernando Giraldo Parra from Tecno Electronic introduces a video on repairing Oster blenders with three speeds. He highlights that Oster blenders use a unique winding system with two gauges of enameled wire, unlike other blenders that use a single wire type. He explains that traditional Oster blenders use gauges 23 and 26, totaling 115 turns, and warns against small, low-quality repairs that can reduce the blender's power.

The video details the process of winding the coils for an Oster blender. Each coil is made with two different gauges of enameled wire (26 and 23). The method involves unwinding two wires simultaneously, resulting in a coil with two starting points (principle 1 and 2) and two end points (final 1 and 2). This process is replicated on both sides of the stator. The importance of correctly marking these eight terminals is emphasized, as it dictates the polarity (north and south) necessary for the magnetic fields to attract.

The video explains the electrical diagram for a 3-speed Oster blender. The speaker clarifies that each coil is represented diagrammatically for easier understanding. The setup includes the field coils, commutator, brushes (carbons), and the power input (220V AC). A 3-speed switch controls the number of active coils for each speed. Speed 1 activates all four coils, leading to higher resistance and lower speed. Speed 2 activates three coils, reducing resistance and increasing speed. Speed 3 activates only two coils, resulting in the lowest resistance and highest speed due to increased magnetic field strength.

The video concludes by reiterating that the described circuit is standard for American Oster blenders. It emphasizes that proper winding, correct wire gauges, and accurate marking of connections are crucial for the blender to function correctly across its three speeds. The continuous path of the current through the coils, without short circuits or opposing polarities, is essential for the magnetic fields to generate the desired speeds.
